Even safer, more efficient and more sustainable. The new Pirelli Cinturato P7, a high performance summer tire, takes advantage of both the legacy of the Cinturato brand – with seventy years of history – and the constant development of the previous generation of the P7. Already available from retailers for the summer, the new Cinturato P7 debuts across the European and Asian market.

FOR DRIVERS SAFETY IS EVEN MORE IMPORTANT

A research commissioned by Pirelli,
and carried out between the end of April and the first days of May on a target of
motorists who use tires from 18 ” up, highlights the
propensity to use one’s own car to a greater extent than in the past,
especially in this phase of necessary social distancing. In China the
68% of consumers say they will make greater use of the car, in Italy
31%, in Germany 20%.

In addition, more than 50% of the sample
interviewee highlighted the desire to change the tire set within
the year to secure your car; among the criteria for choosing,
attention to tire quality and reliability is growing everywhere: the
percentage of users who declare greater attention to the performance of
product safety rises to 59% in Germany, 78% in Italy, 86%
in China.

THE
NEW PIRELLI CINTURATO P7

From the previous generation launched
in 2009 and since then leader of approvals, the Cinturato P7 has been the subject of
continuous updates thanks to the close work between Pirelli and the
major premium car manufacturers. The new generation of Pirelli
Cinturato P7 further enhances the qualities that are most important today
for motorists: safety and efficiency. Pirelli engineers,
through intense Research & Development, have created a
high-tech product capable of overcoming the compromises that
to date they have been typical of tires: thanks to the technologies created for
the new Cinturato P7 could usually be reconciled with each other
divergent, such as wet performance and rolling resistance,
reaching a new technological level and managing to satisfy
motorists and manufacturers. Among the technical innovations, a new compound, equipped
of a sort of “mechanical intelligence”, capable of changing behavior in
based on the operating temperature, almost as if they were two compounds in one.

SAFETY, FIRST OF ALL, BUT ALSO COMFORT AND RESPECT FOR THE ENVIRONMENT

Safety is the characteristic
main of the new new Pirelli Cinturato P7. The new car tire
premium, in addition to improving the dry qualities offered by the predecessor, it
exceeds to a greater extent in wet driving in handling, aquaplane and in
particularly the braking where it records up to 4 meters less than 100 km / h
at the stop. The innovations introduced by Pirelli designers also have
raised the level of acoustic comfort (with less noise produced during the
rolling) and plastic (thanks to the better absorption capacity of the
asphalt bumps). In addition, mileage increases by 6%
practicable, therefore reducing the frequency of tire replacement.
Again in terms of efficiency, the rolling resistance decreases
on average of a rolling resistance class, (-12%), reducing the consumption of
fuel of 4% of the car (measured in the WLTP cycle) and emissions of
CO₂.

THERE
“INTELLIGENT” MIXTURE THAT CHANGES TEMPERATURE-BASED BEHAVIOR

The innovations of the new Cinturato P7
generation start from the main element of each tire: the
tread. The specially created mix is ​​enriched with silica, resins
specifications, which have the task of increasing grip and polymers
functionalized, i.e. chemically modified synthetic elastomeric materials
with the aim of improving the interaction with the silica itself. Such polymers have
the ability to change behavior based on operating temperatures. This
new compound has a form of “mechanical intelligence”, thanks to better
distribution of silica particles and the interaction between them, which
allows you to vary your behavior according to the conditions of
driving and temperature, ensuring the driver an operating window
extremely wide ideal.

THE TREAD BORN IN VIRTUAL REALITY

Each part that makes up the design
tread of the new Cinturato P7 has its own specific function: from the lateral grooves
and longitudinal, whose geometry is designed to evacuate in the most possible way
water is possible as far as the particular shoulder blocks with one
conformation such as to ensure the shortest stopping distances both on dry surfaces
that especially on wet surfaces. Not only that, the design itself and its distribution
stiffness allow to have the best support surface even in
curve, for safe and precise driving in all conditions, favoring the
at the same time also comfort: modeled at first virtually and then
experimentally, the sequence of the steps of the drawing is studied in such a way as to
maximize the comfort, acoustic and plastic, for the motorist.

SPACE
REDUCED BRAKING THANKS TO THE DIALOGUE WITH ELECTRONICS

Another point on which the engineers
Pirelli have worked and the ability of the tread to “dialogue” with the
electronic driver assistance systems, such as the most modern ADAS. In case
ABS, for example, with the same car and tire size, a tread
optimized for operation in synergy with the vehicle’s electronics
allows you to brake first. The tests carried out at the speed of 100 Km / h have
shown that the new Cinturato P7 requires on average up to 4 meters in length
less braking space, equivalent to a 7-10% reduction. The development of the tire in
collaboration with car manufacturers, through virtualization models of
covers, allows you to better calibrate the assistance electronics: as in
case of lane-keeping systems which, if combined with a tire
“Unknown”, may require continuous non-trajectory corrections
being able to predict the behavior of the tire itself. While, if the same
car is equipped with the Cinturato P7 with the marking of the car manufacturer
– developed to equip the specific car – does not require such corrections since the
system can predict their reactions.

WITH
THE NEW MATERIALS, MORE ADHERENCE AND LESS ABRASION

The materials created for the new
Pirelli Cinturato P7 confer greater mechanical strength, though
ensuring adherence in different driving situations. The speed of
reduced abrasion, given by the “high mileage” tread, results in a yield
higher mileage, to the benefit of efficiency and savings for motorists. This thanks to the use
in the mixture of high molecular weight polymers, that is chains of elements
very long chemicals which guarantee the tire better properties
mechanics such as greater abrasion resistance and more durability. Mix it
it was designed parallel to the design, so as to offer an excellent
balancing the “tread system” which gains a footprint on the ground
optimized, reducing the heat generated during rolling and contributing
to increase adhesion and decrease abrasion.

LESS CONSUMPTION AND ENVIRONMENTAL IMPACTS THANKS TO THE LIGHTER AND EFFICIENT STRUCTURE

Having increased endurance
mechanics of the compound, it was not only possible to decrease the material used
for the tread, while maximizing the mileage, but lightening
the entire tire thanks to a meticulous study on materials: less material
means less weight and consequently less rolling resistance and a
more conscious use of resources. This results in less use of
fuel, therefore saving for the motorist and a lower environmental impact.
Pirelli engineers also intervened on the reinforcement materials, without
ask compromises to the structure of the Cinturato P7: the use of ropes for
very high tensile strength allowed to limit the number and
consequently contribute to weight reduction. Contain the weight of the
tire is one of the requests of automotive manufacturers, functional to
compliance with the increasingly stringent emissions targets imposed by regulations.

ELECT,
RUN FLAT AND SEAL INSIDE: PIRELLI TECHNOLOGIES AT THE SERVICE OF CUSTOMERS

The new Cinturato P7 was born with the
best Pirelli technologies, adopted at the request of the manufacturers
for the different models on which the tire is homologated or
of motorists with specific needs. Starting with the latest Elect,
a specific technology package for electric or plug-in cars
hybrid: immediate grip necessary for the particular torque delivery
of electric motors, less rolling resistance to maximize
the autonomy given by the batteries and the reduction of noise to ensure the
benefits in terms of comfort of electric propulsion. In addition, Cinturato
P7 can be equipped with run flat and Seal Inside technologies that allow you to
drive even after a puncture; the first arguing, thanks to the side
reinforced, the weight of the car, the second by injecting a putty that repairs in
autonomy the hole up to a diameter of 4 mm.

THE P7 BELT IS CONFIRMED THE MOST CHOSEN BY CAR HOUSES
PREMIUM IN ITS CATEGORY

The development of the new Cinturato P7 began about 3 years ago and, before the version for the aftermarket, the variants approved by the car manufacturers for the car models arriving in these weeks were born. The new P7 debuts with already over 70 homologations underway and by the end of 2020 it is expected to exceed 100. Each of these homologations requires a dedicated path and development, in synergy with the car makers. In particular, in the “marked” versions for cars with diameters greater than 17 ’’, the Cinturato P7 immediately joins 23 new versions to over 100 of its predecessor, confirming that it is the tire of its category most chosen by premium car manufacturers.
